Don’t have it in my program, yet. I do ground critical care so maybe not the situation you’re looking at but a lot of flight programs are adopting it. It’s great and it should be the next big thing.
Our protocols are starting with using it for placing A-lines, but our doc gives us a lot of freedom to practice. That said I’ve seen it used to confirm ET tubes, identify pneumothorax, guide needles for when performing pericardiocentesis, and assess volume status to guide fluid resuscitation. This is in addition to identifying internal bleeding/ruptured aortas and starting IVs.
Now this isn’t necessarily for your average medic, but if it is a progressive or rural system as long as no one extends their scene time to use it, it could be very useful. But it will be most beneficial in a critical care settings.
